Abi Foundry 4073 Cast Iron Spigot Plug 6 Inch

Product Description

The ABI FOUNDRY 4073 is a 6-inch service weight cast iron spigot plug designed to close off or cap drainage, waste, and vent pipe ends in sanitary sewer systems. Manufactured domestically from cast iron, this plug provides the mass and durability expected in service weight DWV applications. The spigot end inserts into a compatible hub fitting, creating a secure, stable seal. At 4 inches in length and rated for temperatures from 32 to 212 degrees F, it handles standard gravity-flow drain conditions encountered in residential and light commercial plumbing work.

This plug is suited for use in above-ground and below-grade cast iron DWV piping systems where a 6-inch service weight fitting is required. Typical applications include capping cleanout openings during pressure testing, permanently closing unused branch connections, and staging rough-in work before final connections are made. Licensed plumbers working on new construction and remodel projects will find this plug appropriate for standard sanitary drain configurations.

Installation Notes

Installation is performed by licensed plumbers in accordance with the International Plumbing Code and applicable local codes. Shut off water supply and relieve system pressure before working on any connected drain lines. The spigot end is typically joined using standard cast iron compression gaskets or lead-and-oakum methods depending on system requirements. Never force the plug into an undersized or mismatched hub, as this can crack the fitting.
